IMPROVEMENT IN SEEDING-MACHINES.

Specification forming part of Letters Patent No. 23.357, dated March 29, 1859.

To all whom t may concern:

Be it known that I, F. M. Davis, of Footville, in the county of Rock and State of Tis consin, have invented `a new and Improved Seeding-lvlachine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side sectional viewwrof my invention, taken in the line x x, Fig. 2. Fig. 2 is a plan or top view of the same, Fig. 3, a detached plan or top view of one of the seedslides and the slotted bar that operates it.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular platform, which is mounted on wheels B BV, and has a draftpole, B', attached at one end by a pin or bolt, (t. The front end ofthe platform is supported by a caster-wheel, C, the rod b of which passes through the front part of the plat-form and bears against the under side of a lever, D,

' which is secured by a fulcrum-pin, c, to the front part of the platform, the back or inner end of the lever being secured at the desired height by means of a curved rack, E, attached to the platform and passing through a mortise in the lever D, a pin, d, passing transversely through said mortise, serving as a catch. The rack E is attached to the platform A by a joint, e, and a spring, f, bears against the rack E, serving to keep it in connection with the pin (l. (See Fig. l.)

F is a curved bar, which is attached by a fulerum pin or rod, g, to a ledge, h, on the platform A. The lower part of this bar F eX- tends below the platform A, and has a pinion, G, fitted in it, said pinion having a crank, i, at one end of its shaft.

H is a connecting-rod, one end of which is attached to the crank fi, the opposite end being attached to a transverse bar, j, which has two slides, 7c k, attached to it, one at each end. The slides k k are parallel with each other, and they are fitted and work between the front end of the platform A and a board, I, attached to the under side of the platform. Each slide lc has an oblique slot, Z, made in it, and a pin,

my, fits in each slot I, said pins being attached of seed-boxes K K. The seed-slides J are perforated and arranged in the ordina-ry way.V

To the under side of the plat-form A, at its front part and at each side, afurrow-share, L, is attached, said shares being attached to the lower ends of tubes a, which communicate with holes 0 in the bottoms of chambers p adjoining the seed-boxes. The upper end of the bar F passes through a mortise in the lever D. rlhe pinion G, when the seed-distributing device is in operation, gears into a wheel, M, on the axle N of the wheels B B.

The operation is as follows When the niachine is drawn along a reciprocating mot-ion is given the slides k la through the medium of the crank 'i and connecting-rod H, and the oblique slots Z in the slides k give a reciprocating motion to the seed-slides J, which distribute the seed from the boxes K in the usual way, or in a way similar to most reciprocating seedslides. `Then it is desired to stop the seed-distributing device, the driver, from his seat A', throws back by his foot the rack E, and then depresses the lever D. This pushing down of the lever D throws back the bar F, and consequently the pinion Gforward and k lr, and consequently the slides J J, will beinoperative. At the same time the lever D, bearing on the top of the rod b, will as it is depressed raise the front end of the platform A, and consequently the shares L, so that the latter may be elevated free from the ground and the machine drawn along from place to place, the same as any ordinary vehicle. (See red-lines, Fig. l.) The shares also may be adjusted as desired, higher orlower, to make furrows of greater or less depth, by regulating the position of lever D, the teeth of the gearing G M being sufficiently long to admit of such adjustment without throwing said parts out of gear. The usual.covering-shares, L', are employed.

I am aware that reciprocating seed-slides J have been previously used, and also that slides 7c, with oblique slots Z, have been used for operating seed-slides. Iwtherefore do not claim the reciprocating seed-slides, nor the slides lc,- but Ifaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

to seed-slides J J, which work in the bottoms out of gear with the wheel M, so that the slides y The arrangement and Combination of the aster-Wheel C, lever D, spring rack-bar E, iniOn-bar F, pinion G, rod H, slides 7c, and hare L, as herein shown and described, so hat when the bar E is thrown back and lever )is depressed the bar F will carry the pinion l Witnesses: nt 0f gear With Wheel M, and thus render the l S. W. D. PARKER, eed-slides 7c inoperative, While the front part l R. B. TREAT.

0f the machine will be lifted 0n the Gasteinl Wheel andthe shares L raised ont ofthe ground,
